Specification of Letters Patent.

Patented Feb. 25-, 1.908.

To all whom it may concern:

FER, citizen of the UnitedStates, residing at Reading, in the county ofBerks and State of Pennsylvania, have invented certain new and useful Imrovements in Mufiler Cut- Outs, of which the following is aspecification.

This invention has relation to -cut'outs for mufllers, and it consistsin the novel arrange.

ment of its parts as hereinafter shown and described. 1

Strictl speaking, the cut-out is not a portion of t iemufiier butaffords a means for connecting or communicatin the exhaust ipe of anengine with a In er. The cutout is in the form of afitting and isprovided at one-end with a port for connection with the exhaust pipe andat its opposite end with.

a port against which a valve-is designed to operate.- The fitting isprovided at .a point intermediate of its ends with a mufiler port forconnection with a mufiler. .The channel throu h the-fitting is distortedor inclined slight? its lower portion is curved toward the said ort inorder to relieve the valve at the iowerend of the fitting from excesspressure when closed. i

In the accompanying drawing, the

with an exhaust pipe and a mufller.

The 'muflier .1 is of any usual form and the fittin 2 is interposedbetween thesaid mufiler and t 1e exhaust pipe 3; The upperend-ofthefitting 2 is non-circular, as'at 4, andis provided with an opening whichcommuni- 'cates withthe pipe 3. At its opposite end the fitting isprovided with an ope '5;

Said openlng is provided with a' seat 6. e lugs 7 are Located upon theouter'side of the fitting 2 and the'shank .9 is "ivoted to said lug bymeans of a pin "8; e valve 10 is mounted upon the shank 9 and is.adaptedto close against. the seat 6 of the opening 5.

y away from the lateral port,-'and at outlet ports,- said The elementllfis attached at one end to the Be it known that 1, WILLIAM G. SCHAEF-fshankB and'is'adapted, when'drawn, to hold the valve:10 -closed againstthe seat -'6. One

- end of the spring 12 is attached to a stationary point and its otherend is attached to the shank 9. 'Th'esaid spring is under tension andhas a tendency to hold the shank 9 and the valve 10- away from the seat6. All of the .openingsof the fitting are of substantially the samelateral dimensions, and the chan-' nel throu h the fitting isslightlydistorted or-incline away from the lateral opening of the'fittinand atitslower portion is curved toward t e said lateral o ening. Theob-' ject in providing the cined channel as specified is to relieve thevalve 10 and shank 9 from the direct pressure or force of the ex-v haustwhen thesaid valveis closed, and the said exhaust is introduced into'theInufiler.

Thus the valve will not be vibrated against its seat-with inju to thevalve and seat.

What is claime is Ainufiier cut-out comprising afitting having parallelinletand outlet ports, a

swinging valve adapted to close the outlet port, a muffler port locatedbetween and substantially perpendicular to said inlet and outlet orts,all of said ports being of sub s'tantia ly the same area, said fittinghaving a channel leadin from the inlet port tothe channel being bent atan intermediate point andinclined at an angle to said parallel ports andthen curved arou- .ately into alinement with said muflier ort,

whereby the outlet port is relieved o the direct pressure or impact ofthe exhaust ontering the inlet valve.
